Question

Difference between monophyly polyphyly and paraphyly

Answer 1

Answer:

• In cladistics, a monophyletic group, or clade, is a group of organisms that consists of all the descendants of a common ancestor (or more precisely ancestral population).
• Polyphyly is a term in cladistics. It describes a group of organisms whose last common ancestor is not a member of the group.
• In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and all descendants of that ancestor excluding a few—typically only one or two—monophyletic subgroups
